Write an equation for a sine curve that has the given amplitude and period, and which passes through the given point.
Delicious77 [7]

ANSWER

y = 5\sin( \frac{\pi}{3} x  -  \frac{2\pi}{3} )

EXPLANATION

Let the equation of the sine curve be of the form;

y = a \sin(bx + c)

where a=5 is the amplitude and period,

\frac{2\pi}{b}  = 6

This implies that

b =  \frac{2\pi}{6}

b =  \frac{\pi}{3}

We substitute the values we got so far into our equation to obtain;

y = 5\sin( \frac{\pi}{3} x + c)

When we substitute (2,0) we obtain;

0= 5\sin( \frac{2\pi}{3}  + c)

Solve for c.

\sin( \frac{2\pi}{3}  + c)  = 0

\frac{2\pi}{3}  + c =   \sin^{ - 1} (0)

\frac{2\pi}{3}  + c =   0

c =  - \frac{2\pi}{3}

Hence our equation becomes

y = 5\sin( \frac{\pi}{3} x  -  \frac{2\pi}{3} )

The correct choice is D.

(05.02) In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the
Irina18 [472]

<u>☁️</u><u>My Answer☁️:</u>

y = 90°

<u>✧My Step-by-step explanation✧:</u>

The angle x forms a straight line with the both the 50° angle and the 40° angle:

x + 50° + 40° = 180°

x = 90°

Which means…

y = x = 90°
